INTERFILL®? What is it?
The key component of the “Advanced Epoxy Coating Process” is the INTERFILL® material, which is an airworthiness approved material, wherby the mechanical properties are namely based on Epoxy Resins, slightly influenced by the natural characteristics of the individual dry lubricant fillers. Choosing the matching fillers, regarding to the base material of the repaired part and the given conditions, is one of the most difficult steps within our engineers work process. The main criterion of the “Advanced Epoxy Coating Process” is a good wear characteristic, smooth surface quality and good performance against foreign object damages. The INTERFILL® material is manufactured by Lufthansa Technik Intercoat, tested and certified by an approved laboratory to ensure product integrity and reliability.
The main properties of INTERFILL® are:
- Resistance towards fuels, lubricants, solvents, hydraulic fluids, paint strippers, degreasers
- Self lubricating behavior and excellent dry run characteristics
- Usability in a temperature range of -100° C (-148° F) to +320° C (+608° F)
In most applications the INTERFILL® repaired areas have better wear characteristics than the original surface. This results in an improved performance of the complete assembly and/or system.
Your benefits are:
- Salvaging of parts, which normally have to be scrapped, because the conventional repair methods cannot be applied or are too expensive
- INTERFILL® material is applied by hand only. Even sections extremely hard to reach can be repaired
- Repair costs regarding our effort and not piece part price
- Life extension of components, which results in the reduction of maintenance cost
- Improved performance of the repaired component
- Almost unlimited repair repeatability
- Excellent surface finish
